KARSOVROP Virus 🔐 (.KARSOVROP Files) — How to Remove?

The Karsovrop virus falls under the Mallox ransomware family. Malware of this type encrypts all the data on your computer (photos, documents, excel sheets, music, videos, etc) and appends its specific extension to every file, leaving the FILE RECOVERY.txt text files in every folder which contains the encrypted files.

Karsovrop virus: what is known so far?

☝️ Karsovrop is a Mallox family ransomware-type virus.

Karsovrop will append its own .karsovrop extension to every file’s name. For example, an image entitled “photo.jpg” will be changed to “photo.jpg.karsovrop”. In the same manner, the Excel table named “table.xlsx” will be altered to “table.xlsx.karsovrop”, and so on.

In each folder containing the encrypted files, a FILE RECOVERY.txt text file will be created. It is a ransom money note. It contains information about the ways of paying the ransom and some other remarks. The ransom note most probably contains a description of how to buy the decryption tool from the ransomware developers. You can obtain this decryptor after contacting [email protected] via email. That is it.

How did Karsovrop ransomware end up on my PC?

There are many possible ways of ransomware injection.

There are currently three most popular methods for evil-doers to have the Karsovrop virus acting in your system. These are email spam, Trojan injection and peer networks.

• Another thing the hackers might try is a Trojan virus model. A Trojan is a program that gets into your computer pretending to be something legal. For example, you download an installer of some program you need or an update for some program. But what is unpacked reveals itself a harmful agent that corrupts your data. Since the update wizard can have any name and any icon, you have to make sure that you can trust the resource of the files you’re downloading. The optimal thing is to use the software companies’ official websites.
• As for the peer-to-peer networks like torrents or eMule, the danger is that they are even more trust-based than the rest of the Internet. You can never guess what you download until you get it. So you’d better be using trustworthy resources. Also, it is reasonable to scan the folder containing the downloaded objects with the antivirus as soon as the downloading is finished.

How to remove ransomware?

It is important to note that besides encrypting your files, the Karsovrop virus will most likely deploy Vidar Stealer on your machine to get access to credentials to different accounts (including cryptocurrency wallets). The mentioned spyware can derive your logins and passwords from your browser’s auto-filling data.

How сan I avoid ransomware attack?

Karsovrop ransomware doesn’t have a superpower, so as any similar malware.

You can protect your system from its infiltration taking several easy steps:

• Ignore any letters from unknown senders with unknown addresses, or with content that has nothing to do with something you are expecting (how can you win in a lottery without even taking part in it?). If the email subject is more or less something you are waiting for, scrutinize all elements of the suspicious letter with caution. A fake email will surely contain mistakes.
• Never use cracked or unknown software. Trojans are often distributed as an element of cracked software, possibly under the guise of “patch” which prevents the license check. But dubious programs are difficult to tell from trustworthy ones, as trojans sometimes have the functionality you seek. You can try searching for information about this software product on the anti-malware forums, but the optimal way is not to use such software.
